CONSERVATIVE MANAGEMENT OF HYDROCELE- CASE REPORT

In this case report, we present an event of a 65-year-old gentleman with a diagnosed solitary oval swelling of the size 6×4 cm present in the right side of the scrotum by ultrasonographic images. Hydrocele under tension may be at high risk of acute rupture of testis of reducing the spermatogenesis, and surgical correction may be the best therapeutic opinion in this case. We expectantly managed the patient's massive hydrocele and encountered by hydro celotomy and no complications throughout the course of his recovery.Keywords: Hydrocele, Ultrasonographic Image, Hydrocelectom

Path Double Covering Number of Product Graphs

A path partition or a path cover of a graph G is a collection P of paths in G such that every edge of G is in exactly one path in P. Various types of path covers such as Smarandache path k-cover, simple path covers have been studied by several authors by imposing conditions on the paths in the path covers. In this paper, We study the minimum number of paths which cover a graph such that each edge of the graph occurs exactly twice in two(distinct) paths

EFFECT OF PAROXETINE IN ANXIETY DISORDER AMONG SCHOOL DROPOUT TEENAGER IN SOUTH INDIAN POPULATION

Objective: Anxiety disorders are the most common group of psychiatric illnesses in children. This study is to observe the effectiveness of Paroxetine in anxiety disorder among teenagers in South India population using Hamilton Anxiety Rating Scale (HAM-A) and to screen the possible risk for paroxetine in anxiety disorder among teenagers. Methods: This study is a prospective observational study that was conducted for a period of 6 mo. Of 84 teenage patients with anxiety disorder assessed using Hamilton Anxiety Rating Scale (HAM-A) were followed-up in an outpatient psychiatric ward. Study population includes both sexes, age group between 13 to 19 y, Teenage patient receiving paroxetine for anxiety disorder were included and patients unwilling to give written informed consent or assent form were excluded. Results: Out of 84 patients the prevalence of symptoms before the drug treatment, 65 patients were falling in very severe category, which was assessed by HAM-A scale. Then reassessed with drug Paroxetine at week 4 and week 8. There was a drastic reduction in the prevalence of symptoms in week 8 than compared to week 4. A significant reduction in body weight was also observed during the study period. Among various side effects, nausea was the prominent risk found during the study. Conclusion: The present study demonstrated that paroxetine is effective and well-tolerated for the treatment of various types of anxiety disorder in teenagers with few side effects

A Note on Isolate Domination

A set $S$ of vertices of a graph $G$ such that $\left\langle S\right\rangle$ has an isolated vertex is called an \emph{isolate set} of $G$. The minimum and maximum cardinality of a maximal isolate set are called the \emph{isolate number} $i_0(G)$ and the \emph{upper isolate number} $I_0(G)$ respectively. An isolate set that is also a dominating set (an irredundant set) is an \emph{isolate dominating set} \ (\emph{an isolate irredundant set}). The \emph{isolate domination number} $\gamma_0(G)$ and the \emph{upper isolate domination number} $\Gamma_0(G)$ are respectively the minimum and maximum cardinality of a minimal isolate dominating set while the \emph{isolate irredundance number} $ir_0(G)$ and the \emph{upper isolate irredundance number} $IR_0(G)$ are the minimum and maximum cardinality of a maximal isolate irredundant set of $G$. The notion of isolate domination was introduced in \cite{sb} and the remaining were introduced in \cite{isrn}. This paper further extends a study of these parameters

Influence of Nitrogen and Phosphorus Fertilization on Fruiting and Yield Characteristics in Ratoon Crop of Banana (Musa spp. AAA) Cv. Grande Naine

In ratoon crop of banana cv. Grande Naine, date of shooting could be advanced by 35 days with application of 200g N in 5 splits + 60g P2O5 (86 days), compared to 300g N in 5 splits + 60g P2O5 (121 days). Subsequently, date of harvest also got advanced by 53 days, and fruits were harvested on 9th December in the same treatment. Higher dose of N fertilization delayed shooting and harvesting period, taking 121 days for shooting and 145 days from shooting to harvest in the treatment 300g N (5 split doses) + 90g P2O5. Various N and P treatments affected bunch weight and number of hands per bunch significantly. Although N and P combination-treatments had no significant effect on bunch weight or number of hands per bunch, application of 200g N in 5 splits and 60g P2O5 per plant gave maximum bunch weight (18.11kg) and number of hands per bunch (10.61). Minimum bunch weight (15.37kg) and the least number of hands per bunch (7.08) were obtained with 150g N in 5 splits + 90g P2O5. Hand-weight (2.20kg), number of fingers per hand (19.75), and finger length (20.30cm) was highest with application of 200g N in 5 splits + 60g P2O5 per plant. Least hand-weight (1.64kg), number of fingers per hand (15.77), and finger-length (17.92cm) was recorded with 150g N in 5 splits + 90g P2O5. Bunch weight, number of hands per bunch, hand-weight and number of fingers per hand too was affected significantly with sole application of nitrogen or phosphorus

Biocompatibility studies on lanthanum oxide nanoparticles

Lanthanum oxide nanoparticles (LONP), a rare earth metal oxide, have unique properties that make them a suitable candidate for several biomedical applications. We investigated certain key in vitro and in vivo biocompatibility endpoints on LONP. LONP were cytotoxic in in vitro assays and predominantly exerted their action via release of reactive oxygen species. These nanoparticles were neither irritants nor sensitizers in a rabbit model. LONP extracts did not exert any acute systemic toxicity effects in mice. On the other hand LONP exerted toxicity to the liver following oral administration, suggesting that these particles are absorbed from the gastrointestinal (GI) tract and deposited in the hepatobiliary system. LONP did not induce any mutation in the Ames test both in the presence or absence of S-9. These observations provide a base line biocompatibility and toxicity data on LONP. The current findings will also be useful in defining standards for nanoparticle containing devices. © The Royal Society of Chemistry

Genotoxicity evaluation of medical devices: A regulatory perspective

This review critically evaluates our current regulatory understanding of genotoxicity testing and risk assessment of medical devices. Genotoxicity risk assessment of these devices begins with the evaluation of materials of construction, manufacturing additives and all residual materials for potential to induce DNA damage. This is followed by extractable and/or leachable (E&L) studies to understand the worst case and/or clinical exposures, coupled with risk assessment of extractables or leachables. The TTC (Threshold of Toxicological Concern) approach is used to define acceptable levels of genotoxic chemicals, when identified. Where appropriate, in silico predictions may be used to evaluate the genotoxic potentials of identifiable chemicals with limited toxicological data and above the levels defined by TTC. Devices that could not be supported by E&L studies are evaluated by in vitro genotoxicity studies conducted in accordance with ISO10993-3 and 33. Certain endpoints such as ‘site of contact genotoxicity’ that are specific for certain classes of medical devices are currently not addressed in the current standards. The review also illustrates the potential uses of recent advances to achieve the goal of robust genotoxicity assessment of medical devices which are being increasingly used for health benefits. The review also highlights the gaps for genotoxicity risk assessment of medical devices and suggests possible approaches to address them taking into consideration the recent advances in genotoxicity testing including their potential uses in biocompatibility assessment

Super Fibonacci Graceful Labeling

Abstract: A Smarandache-Fibonacci Triple is a sequence S(n), n ≥ 0 such that S(n) = S(n−1)+S(n−2), where S(n) is the Smarandache function for integers n ≥ 0. Certainly, it is a generalization of Fibonacci sequence. A Fibonacci graceful labeling and a super Fibonacci graceful labeling on graphs were introduced by Kathiresan and Amutha in 2006. Generally, let G be a (p,q)-graph and {S(n)|n ≥ 0} a Smarandache-Fibonacci Triple. An bijection f: V (G) → {S(0), S(1), S(2),..., S(q)} is said to be a super Smarandache-Fibonacci graceful graph if the induced edge labeling f ∗ (uv) = |f(u) − f(v) | is a bijection onto the set {S(1), S(2),..., S(q)}. Particularly, if S(n), n ≥ 0 is just the Fibonacci sequence Fi, i ≥ 0, such a graph is called a super Fibonacci graceful graph. In this paper, we construct new types of graphs namely Fn ⊕ K + 1,m, Cn ⊕ Pm, K1,n ⊘ K1,2, Fn ⊕ Pm and Cn ⊕ K1,m and we prove that these graphs are super Fibonacci graceful graphs
